What is the difference between a laser light and the light given off a filament lamp?
Laser light is said to be coherent; regular light such as the type produced by an incandescent bulb is incoherent. In coherent light, all the wavelengths are the same, and all the directions are the same, everything lines up and is perfectly uniform. With incoherent light, you get a messy mixture of wavelengths and directions.
Light from a laser is collimated - i.e. aligned such that all the light rays are oriented parallel to each other. For this reason, you do not see laser light unless some of it is deflected by striking a something in its path or you are looking directly at it. In a filament lamp, the light rays are oriented in nearly all directions.

What is difference between three and four level laser?
The main difference between three and four level lasers lies in the energy levels involved in the lasing transition. In a three-level laser, the lasing transition occurs between the ground state and an excited state, while in a four-level laser, an additional intermediate energy level is used to facilitate the lasing process. This intermediate level enables four-level lasers to operate more efficiently at higher power levels compared to three-level lasers.
What is the main difference between laser and ordinary white light?
The main difference is that laser light is coherent, meaning the light waves are aligned and moving in a single direction, while ordinary white light is non-coherent, with light waves traveling in random directions. Laser light is also monochromatic, meaning it consists of a single color, while white light contains a mixture of different colors.
What is the difference between a laser pointer and an infrared laser pointer?
An infrared pointer uses light that is mainly in the infrared spectrum, and so is mostly invisible to humans. A laser pointer in general refers to any device using a beam of light to mark an object. Both use the same basic technology. The only difference is the wave length. IR lasers are outside of the visual spectrum where as standard laser pointers are within the visual spectrum.
Is there a difference between laserjet paper and normal paper?
There are a number of differences between laser copy paper and normal copy paper. Laser copy paper is heavier and thicker, it is brighter, it gives a smoother finish and hence a higher quality print, it reduces show through from the other side of the page, it is more expensive.
What is the difference between a laser light and the light beam from a white flashlight?
A laser light is coherent, meaning its waves are all in phase and directional, giving a narrow beam. In contrast, light from a white flashlight is incoherent and spreads out in various directions. Laser light also has a single color (wavelength), while white light contains a mix of colors.
What is the difference between a river and a laser?
A laser is man-made, a river is natural.
What the difference between the laser unit of Noritsu QSS32 and QSS34?
There is no difference.
What is the difference between a laser printer and and a ink printer?
An ink jet printer simply prints. A color laser copier COPIES. This is the significant difference between the two.
What is the difference between personal and shared laser printer?
nothing
What is the difference between a ink jet printer and a color laser copier?
An ink jet printer simply prints. A color laser copier COPIES. This is the significant difference between the two.
How does a machine tell the difference between one dollar and five dollars?
Vending machines have laser scanners that can tell the difference between the bills.
Is there a difference between laser eyes and heat vision?
Heat vision is like laser eyes, but using it in a heating way... Laser eyes are shooting lasers out of your eyes
What is the difference between a laser card and a debit card?
Both have different use
Difference between optical and laser mouse?
While both optical in laser mice require a light source in order to detect movement, the difference between the two technologies are optical mice use LEDs as their light source while laser mice use infrared laser that cannot be seen by the human eye. Laser mice are also much more precise than optical mice due to a higher DPI tolerance.
What is the difference between continuous and pulsed wave laser?
Continuous I assume would mean a constant flow of light from the laser in the form of a wave train. Conversely, a pulse is only a single wave emitted by the laser.
What is the difference between a laptop wireless optical mouse and a wireless laser optical mouse?
The laser wireless optical mouse has laser sensors to direct the mouse on the screen as without it is a roll ball used to do so.
Difference between a laser and a burning laser?
Burning lasers create more heat than normal lasers. Strictly speaking, Laser include burning laser. Burning lasers are powerful laser pointers like 300mW or above, they can burn objects like paper and tapes.
